We have the 366FL. Love the floor plan.
The floor in the kitchen was bubbled from day one. I elected not to have the dealer repair the problem due to the cabinets being removed for the repair. We also know that when the warranty was out, we would replace the floor covering with a high quality vinyl tile. Even if the bubble was not there, I would have made the change. The new tile does not show dust and dirt as bad and we prefer the slate tile look.
We do not dry camp, however, I did add a second battery. The refrigerator and other systems seem to have a large power drain.
Being from West Texas, I had a tinting company do the windows. This was for both heat and to reduce light in the bedroom. When we purchased ours, I did not know that you could order a 5th wheel with 3 AC units. Learn that information from a Forest River rep last week at a RV show. That AC would be nice in the living room. The other information we gathered at that show is that we truly love our 5th wheel and glad we made the purchase.
I blow the fuse for the remote control, easy fix. That is the only other problem I have had. Pulled the trailer 3527 miles last year and stayed 63 nights.
The basement storage is not every good, but we still manage the tote everything we have for the last 3 trailers. We did not get the underneath storage, nor plan to add it.
You will love your purchase.
